Measurement-Induced Long-Distance Entanglement of Superconducting Qubits using Optomechanical Transducers
Ondřej Černotík, Klemens Hammerer
Although superconducting systems provide a promising platform for quantum computing, their networking poses a challenge as they cannot be interfaced to light---the medium used to s…
Satisfying the Einstein-Podolsky-Rosen criterion with massive particles
J. Peise, I. Kruse, K. Lange +8
In 1935, Einstein, Podolsky and Rosen (EPR) questioned the completeness of quantum mechanics by devising a quantum state of two massive particles with maximally correlated space an…
Exploring Interacting Quantum Many-Body Systems by Experimentally Creating Continuous Matrix Product States in Superconducting Circuits
C. Eichler, J. Mlynek, J. Butscher +4
Improving the understanding of strongly correlated quantum many body systems such as gases of interacting atoms or electrons is one of the most important challenges in modern conde…
Optimal state estimation for cavity optomechanical systems
Witlef Wieczorek, Sebastian G. Hofer, Jason Hoelscher-Obermaier +3
We demonstrate optimal state estimation for a cavity optomechanical system through Kalman filtering. By taking into account nontrivial experimental noise sources, such as colored l…
Violation of Bell's Inequality in Electromechanics
Sebastian G. Hofer, Konrad W. Lehnert, Klemens Hammerer
Opto- and electromechanical systems offer an effective platform to test quantum theory and its predictions at macroscopic scales. To date, all experiments presuppose the validity o…
Adiabatic Elimination of Gaussian Subsystems from Quantum Dynamics under Continuous Measurement
Ondřej Černotík, Denis V. Vasilyev, Klemens Hammerer
An ever broader range of physical platforms provides the possibility to study and engineer quantum dynamics under continuous measurements. In many experimental arrangements the sys…
